diagnosed ankle sprain grade 2C on Oct 20, 2012. Xray showed no fracture. Saw ortho, did PT, Still have on and off again pain and swelling, and now have on and off hard cyst like bumps on bottom of foot and on and off again burning very painful pain in toes. Concerned about misdiagnosis

1. Since Xray of your ankle was normal, clinically you might have been diagnosed as Ankle sprain. If still you have on & off pain & swelling in your ankle, then its better to confirm with an MRI of your Ankle. MRI will definitely show whether there is any sprain of ankle ligament(s) along with the severity of injury.

Till you take MRI continue to use ankle brace, avoid walking on rough surfaces, avoid using stairs or running or jogging.

2. Small cystic bumps on your foot are most commonly due to Plantar fasciitis or Plantar fibromatosis. Differentiating between these two diseases requires clinical examination by your doctor. Both these conditions are benign.

Plantar fasciitis might need some shoe/slipper modification. Plantar fibromatosis can occur in patients with family history or those suffering from Diabetis mellitus or epilepsy etc., MRI of foot might help in diagnosing the condition.

I would suggest you to discuss with your doctor and get yourself examined clinically and then proceed.
